Introduction: The study investigated dimensional relationships between the sphenoid and maxillary sinuses and other selected craniomaxillofacial structures by using traditional cephalometric and volumetric procedures based on cone beam computed tomographic (CBCT) data. Methods and Materials: A retrospective three-dimensional (volumetric) and two-dimensional (conventional cephalometric) analyses were conducted on CBCT datasets of 27 subjects who met the inclusional criteria from a sampled database of 2,290 individuals. Subjects were divided into 3 groups: (1) pre- fused spheno-occipital synchondrosis < 18 years (n=8), (2) fused spheno-occipital synchondrosis < 18 years (n=9), and (3) = 18 years with fused spheno-occipital synchondosis (n= 10). Results: Differences between studied groups were found for linear and angular measurement. Specific correlations were found between certain topographic and internal measurements, and some sinus dimensions and other selected craniomaxillofacial structures. Conclusion: Dimensional correlations exist between the sphenoid and maxillary sinuses and development of other selected craniomaxillofacial structures.
